Yep, that's me

Thanks for the information -- really appreciate it.
The Reading admission data is quite informative. Looking at the results for 2018 entry:
* 737 sat at Reading, 238 sat elsewhere, 975 in total
* 317 qualified * 195 qualified and in catchment
So, 317/975 -- or about 32% -- of the entrants passed the threshold. This is quite similar to the 30% bracket in Bucks.
Looks like both tests are equally difficult. I was under the impression that Reading School was more difficult to get into than, say Aylesbury Grammar. Huh...

Therefore other things to bear in mind.
You’ll need to move into the catchment area before the test for Reading and, I think, shortly after the test for Bucks for most schools (one Bucks School has a stricter time frame and you need to be in earlier, but I’m not from Bucks so others will give you better info).
Look at other schools in the area, you’ll need to make sure you are happy with alternative schools if your DC doesn’t get a place. Bear in mind that Bucks is a fully selective county so the alternatives to Grammars may not be great depending on the area you are looking at. Again others form Bucks will give you a better picture.
